` Specification of Letters Patent.

Patented Dec. 31,1912.

To all whom 'it may concern:

Be it known that I, THOMAS G. PLANT, a citizen of the United States, residing at- Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in VVelt-Shoe-Preparing Machines, of which the following descri tion, in connection with the accompanying rawings, is a specification, like letters on the drawings representing like parts.

The invention to be hereinafter relates to machines for treating boots and shoes, and more particularly to machines for preparing the shoe to receive the welt.

As well known by thoseskilled in the art, the shoe upper is usually secured to the insole and last by means of tacks partially driven into the last, and during the attachment of the welt to the upper and insole these tacks frequently cause trouble, as by contact with the needle and the like.

The aims and purposes of the present invention are' to provide a machine which shall prepare the lasted shoe to lreceive the .welt without the defects and objections arising from the presence of the lasting tacks, all of which will best be understood fromthe following description and accompanying drawings of one form or embodiment of i means for lcarrying the invention into practical efect, it being understood that the in-v vention is not restricted to such details as forth by the claims. l In t-he drawings :'-Figure` l is a front elevation of `a `machine embodying the features of the present invention, some `'of the parts being broken raway;,Fig. 2 is an enlarged sectional .view taken substantially ony they .ticularly the` stitchA forming mechamsm,

other parts being purposely omitted; Fig. 3

is an enlarged section onthe line 2-2 of Fig. 1, showing the tack pulling mechanism, the stitc forming `mechanism-being omitted; Fig. 4 -isa view similar to-Fig. B'with the parts ina different position; Fig. 5 is adetached detail view lookingl in the direction-of the arrow, Fig. 3;"Fig. 6 is a section on the line 6.-"-6 of Fig 3; Fig. 7 is a detail perspective View showing the sewing andtack pulling-instrumentalitles in describedtheir associated relation with the shoe; Fig. 8 is an enlarged section on the line 8-8 of Fig. 1, showing the clutching devices for controlling the tack pulling instrumentalities; Fig. 9 is a view similar to that of Fig. 8 with the parts in a different position; Fig. 10 is a detached detail view showing the means for supplying moisture to the channel of the shoe sole; Fig. 11 is a detached detail showing the means for initiating the jaw closing and tack pulling movement; and Fig. 12 isfa diagrammatic` view illustrating the general movement o the tack puller.

The present invention contemplates the association of the upper with the insole for the reception of the welt and the action of the welter without the presence of tacks or like fastening means holding the upper and insole in associated relation.

As one form of the present invention means are provided for securing the upper and insole by a series of stitches and withdrawing from the lasted shoe the lasting tacks, so that when the lasted shoe is pre-4 sented to the welter, the well known objections to the presence of the lasting tacks will be avoided.

The machine frame maybe of anyusual- As 'a convenient arrangement for descrip-y -tion the sewing 1nstrumental1t1es may be first brought to attention. Mounted in suitable bearings in the head of the machine is a sewing shaft 4,'Figs. 2, 3 and 4, which may be appropriately driven from anyssuitable `source of power by means substantially as set forth in my application, Ser. No. 437,817,

ltiled June'11,1908, wherein a clutch member 7 is secured to said sewing shaft so as to otate therewith, and has associated therewith a loose member, together constituting an ap-vpropriate form of clutch for connecting` and ldisconnecting the sewing shaft and drlving means. l Thehub 6 of the loose clutch member is engaged by the upper end of an loperating lever 10 pivotally mounted on the Amay be had. Likewise,

main frame at 1l and having its arm 12 connected by a rod 13 to asuitable treadle 14, Fig. 1, the construction being such that upon depression of the treadle the clutch members on the sewing shaft may be brought into operative relation, all as set forth more fully in my prior application, to which reference as set forth in my said application, there is provided a stop finger 15 adapted to be engaged by a suitable stop arm, as pointed out in my said application, whereby the operative parts of the machine may be brought to rest gradually and the main shaft reversed. Suitable means may also be provided, as, for instance, the hand lever 16, arm 17, intermeshing segments 18 and treadle rod 19, all as fully eX- plained .in my said prior application, .for permitting hand manipulationl of the machine without danger of being power driven.

Since the parts so far described form no essential of the present invention and are clearly and fully set forth in detail in my prior application referred to, further elucidation herein will bey unnecessary.

Having reference more particularly to Fig. 2, the needle 20 of any usual type is suitably supported by the needle segment 21 and passes through a guide 22, said segment having connected thereto a link 23 pivoted at 24 toa lever 25 fulcrumed on the machine frame at 26 and having at its free end a roll l27 for engagement with the cam path 28 carried by a suitable cam disk secured to the main sewing shafty 4, so that upon rotation of the shaft the needle 20 will be given the characteristic movements for passing through and withdrawing from the work.

The looper arm 29, Fig. 2, may be of any usual or desired character and is appropriately secured to the end of a looper shaft 30 by means of a nut 31, said shaft extending rearwardly, as indicated in Fig. 2, and pivotally connected at 32 to the upper end of a looper lever 33 which is itself pivotally mounted at 34 to the machine frame. The

looper lever 33 carries a roller 35 adapted to I engage a, cam-path 36 carried by a suitable cam element and secured to the sewing shaft 4. Surrounding the looper shaft 30 is a sleeve 37, Fig. 2, which extends rearwardly and has securedthereto aclamp 38, the end 39 of which engages a pin or stud 40 projecting from the arm 41 mounted to rock upon the sleeve 37 as at 42, saidfarm being extended,

as at 43, and carrying a roll 44 which engages a suitable peripheral cam whereby the sleeve 37,-- and perforce the looper shaft, is

givenv a rocking movement,"fsaid sleeve 37 and looper being connected bymeans of' a hea-d 45 carried by the sleeve an'd'secured to the looper'at 46. Obviously any appropri-v ate means may. be employed to give t-he described characteristic movements to the needle and looper.

vout of'axial ali-nement therewith is 75 which is embraced by a .suitable collar 76 connected` by a link 77 to the end of an Secured to the machine head is a fixed channel guide 47, Fig. 2, said channel guide having, as indicated in Figs. 7 and 10, an opening or passageway 48 for suitable tempering fluid supplied thereto through a connection 49 from a tank 50, Figs. 1 and 10. A valve 51 is interposed between the tank 50 and the channel guide and-has connected thereto an arm 52 which is joined "by a link 53 to an arm 54 pivoted at 56 and having a slot 55 for adjustment of the link 53.v The arm 54 is connected to `the'arm 57 which is appropriately joined by a rod 58 to the treadle 214, the construction being such that, upon depression of the. treadle, the valve 51 will be opened and li uid be permitted to ow into the channel of means for'closing the valve when the machine stops, the sewing shaft 4 has secured thereto, Fig. 10, a valve operator 59 provided with a shoulder 60 adapted to engage the shoe sole. As a a pin 61 carried by an arm 62 pivoted at 63 l to the arm 54, the construction being such that, upon movement of the valve operator 59 in the usual direction for the sewing op eration, t-he pin 61 'will ride idly over the surface thereof, but upon reverse rotation of the shaft the shoulder 60 will engage-thepin as will be readily unl 61 and close the valve, derstood. l The present invention contemplates connecting the upper to the insolev by a series of stitches which, if desired, may be longer than usual, that is, in the nature of basting stitches. To this end the present invention contemplates feeding the work positively the desired .distance between stitches by means .0f an instrumentality that will engage the work-and after each Stitch give it its proper feed movement. v-In the present form of the invention the feeding element comprises a spudger 64, that is, a sharp pointed instrument, carried at the lower end of a rock shaft 65 properly journaled in the machine head. The rock shaft 65 has secured thereto collars 6.6 and 67, Fig. 2, between which is a sleeve 68 connected to a lever 69 fulcrumed on the, shaft' or stud. 70, said shaft having projecting rearwardly the arm 71 connected at 72 to a lever 73 fulcrumed at 26 on the machine frame and having its ibo free end 74 provided with a roll for engagement with the suitable cam track carried I yby the cam element secured to the main sewing shaft 4, the construction being such that upon rotationV of the shaft 4 appropriate rising and falling movement will be imparted to the feeding element or spudger.

Connected to the upper collar 67, Fig. 2, the pin actuating'lever 78 pivoted at 79 to the machine Aframe and having its arm 80 provided with a roll81 for engagement' with a suit-A able cam element for imparting to said lever 78 appropriate rocking movement, the construction being such that upon operation of the sewing shaft 4 the spudger will be given the necessary rising and fallin and oscillatory movementsv to feed'the wor In order that the spudger may appropriately feed the work a desired stitch length, the spudger isgiven a double feeding 84, one end of which is secured to the machine frame and the other end to the gage carrier 82, normally acts to move the gage into forward or operative position. As a means for holding the gage in operative position it is provided with a series of ratchet teeth 85 adapted to be engaged by a lock 86 carried by one arm of a bell crank lever 87, Figs. 3 and 4, the otherarm of said bell crank being engaged by a toe 88 carried by the lever 89, said lever 89 having a roll 90 bearing upon a cam 91, Figs. 3 and 4, secured to the main sewing shaft 4, the construction being such that upon rotation of the cam 91 the back gage will be suitably locked and unlocked for holding it in its operative position 'to` allow proper action of the needle.

From the construction thus far described it will be apparent that upon depression of the treadl 14 themain sewing shaft will be set in operation and the sewing instrumentalities, hereinbefore described, will be given their characteristiclaction to cause the needle to pass through the work, as indi.

cated in Fig. 7, and secure the upper and insole in their associated relations, itybeing understood that the sewing instrumentalities have associated with them a suitable tak"e` .up l92y and tensionI wheel 93; and as each stitchffis yformed that.l the spudger by its duplicate movement will serve to feed the work the desired length of the next stitch.

As ,A hereinbefore pointed "out, when the Y uppeiginsole `and'last are assembled, or in other words when the shoe is lasted, a seriesl of! tacks are driventhrougli 'the upperl and insole into-the last to hold the parts inas- 4sociated relation. These'tackjsjusually pro- *jectfsomelittle distance from thefsurface of the workv and` fthe-.present '-invention con templates-,the withdrawal of these tacks' in further y, preparing lthelasted shoe forI the Welting operation. A l i `pullin iication may be known as the tack pulling or sleeve shaft. v

The tack pulling or sleeve shaft 94 is appropriately driven by means of a belt 95, Fig. 1, from a suitable source of power, a suitable friction clutch being interposed between the pulley 96 upon which said belt runs and the tack pulling shaft 94. The preferred form of clutch connection between the driving pulley 96 and the shaft 94 is such that when one member of the clutch is held from rotative movement the clutch action or yoperative connection between the driving member and the shaft shall be interrupted, and when such member is free to act it will automatically connect the clutch members and driving shaft to causeoperative relation between them. A usual and common form of such device, and one well understood in the art, is known as the Horton F clutch, a form of which is described in patent to Stewart, No. 871,967, Nov. 26, 1909, and

this, or so much thereof as is necessary to,

make clear the present invention, is indicated in the drawings, its details of structure being well understood, needing no further elucidation.

Before proceeding with the detailed 'description of the means for controlling the clutch for the tack pulling shaft for operat.

ing the tack pulling element, it may be well to refer to the characteristics of the tack puller itself.

`Mounted to swing upon a fulcrum or pivotal support 97 is an arm 98 pivotally connected at 99 to a jaw carrier 100. Extending longitudinally through the jaw carrier is a shaft 101 having secured thereto the movable vjaw 103, Figs..3, 4 land 7. rlhe opposite end of said jaw/'carrying shaft 101 is provided' with an offset or crank arm 102 adapted to be secured to a slide rod 104 movable in suitable bearings 105"of a yoke 106, said yoke 106y being pivotally mounted at y10,7 on the arm 108 mountedto rock on the stud shaft 109. Secured to the hub of thearm 108 is a roll carrying arm 110 carrying a roll 111 adapted to' bear upon the peripheral portion of a cam 112 'secured' to the'ta'ck that i the jaw carrier-is' held inxed posi-` shaft, the construction 'beingsuch tion and the cam 112 isy caused to act upon lthe roll 111gthe movable jaw will befswung 'with its shaft 101 into and out of operative rrelation with a coperating fixed jaw to be lpresently described.

Loosely mounted shaft'101`is the `jaw 113, Fig. 7, which for identification maybe knownjas the fixed jaw. Said jawll has a foot portion 114 adaptedV to overlie 'the work, as indicated in Y 412.5: upon the `jaw carrying Fig. 7, and to meet any tack that may be projecting from the upper. Rising from the fixed jaw 113 is an arm 115 having its end 116 normally in contact with the end 117 of a bell crank lever 118, Figs. 7 and 11, pivoted at 119, Fig. 11, and having its arm 120 connected at 121 to a link 122 pivoted at 123 to one arm` of a lever -124 fulcrumed at 125 and having jointed to/ its opposite end the trip 126, Figs. 8, 9 and 11, the construe` tion being su'h that should the fixed jaw 113 be met by a tack, as indicated in Fig. 7, as the shoe is fed by the spudgeraduring the sewing operation, said jaw 113 will be moved on its fulcrum a distance defined by the stop 127, Fig. 7, thereby act-ing uponthe arm 118 of the bell crank and moving the trip 126 for a purpose that willpresently appear.

Secured to the tack pulling shaft 94, Figs. 3 and 4, is an eccentric 128 embraced by an eccentric strap 129 carried by an arm 130 which is pivotally connected at its end 131 to the jaw carrier 100, the construction being such that upon rotation of the tack pulling shaft, in a manner to be presently de-` scribed, the eccentric and the-cam' 112 will operate by their combined action to give to the tack pulling jaws their characteristic tack pulling, tack releasing and returning movement to initial position, all-as will presently appear. A j "ixedly mounted on the shaft 109 is a bell y I' crank lever vone arm 132 of which has a bifurcated end 133 which embraces the'upper end portion of the treadle rod 13, Figs. 3,

, 4 and 8, said bifurcated end being preferably disposed between adjusting nuts l134 and 135 appropriately screw-threaded to the end of the said treadle rod. The downwardly extending arm 136 of said bell crank is connected at 137, Figs. 3 and 4, t'o an` arm 138 pivoted at 139, said arm 138 having a in 140 which is engaged in the slot 141 of the back gage 83, the construction being such that upon depression of the treadle the bell crank lever will be turned and move the pin 140 to the left, Figs. 3 and 4, thereby permitting the back ga e 83 to move to operative position.

Secured to i. and projecting upward from the shaft 109 is the stop arm142, Figs and 9, having a block 143 provided with a shouljder to engage the stop lug 144 on the member 145 of the Horton clutch. The block 143 is preferably supported by the stop -arm 142 yieldingly, .as by means of a spring 146 surrounding the stud 147 which asses through the block 143, said spring bearing at its lower end upon an appropriate shoulder 148 of the stop arm. From the construction thus far described it will be apparent that upon depressionI of the treadle rod 13 the stop arm4 142 will be Withdrawn from thel stop 1ug144 on the clutch member ,145, thus freeing said clutch member and permltting vthe clutch member 145 will ond stop arm 149, Figs. 8 and 9, which may be similarly constructed to the stop arm 142 and carry the yielding block 150 with an appropriate shoulder 151 to contact with the stop lug 144 on the clutch member 145, a spring 152 normally acting to hold the stop arm 149 in depressed position, as indicated in Fig. 8.

The shaft 94 carries an eccentric 153, Figs. i

8 and 9, surrounded by an appropriate eccentric strap carrying an arm 154 provided at its lower extremity with a hooked end 155 adapted to engage with a lroll 156 projecting from the stop arm 149, the arm 154 being held in normal engaging position by means of a spring 157, Figs. 8 and 9, the construction being such that under normal conditions, as indicated in Fig. 8, the stop arm 149l by virtue of the position of the eccentric 153 will be in lowered position, and the stop lug 144 will rest upon the shoulder of the block 143. v

Upon depression-of the treadle'rod 13 andconsequently the withdrawal of the stop arm 142 from engagement with the stop lug 144, be freed to move into operativerelatio'n with its companion l member and rotate the shaft 94. As the shaft 94 rotates from the position indicatedin Fig. 8 to that indicated in Fig. 9, the eccentric 153 will lift the arm 154 and move the stop arm 149 to position the shoulder 151 of the -block 150 for contact with the stop lug 144 of the clutch member, and thereby disengage the clutch from operative engagement with the shaft 94 upon a sub- -stantially one-quarterI` rotation of said shaft.\

Such rotation-of the shaft 94 acting through the eccentric 128 and cam 112, Figs. 3 and 4, will move the jaw carrier 101 into pos1t1on,

.as indicated in Figs. 3 and 7, with the jaw 11'3 in the path of movement of the line of tacks securing the upper. to the insole. So

long as the parts remaln undisturbed in this position by the absence of tacks in the shoe, the tack puller remains'in its normal or tack engaging relaion, asv indicated in Flgs. 3

land 7. As the shoe continues to be fed step..

by step by the spudgeras hereinbefore described, and the tack meets the foot portion 114 of the jaw 113 the positive feed of the shoe will cause the tack to swing the jaw 113 clockwise, as indicatedv in Fig. 7, thereby moving the arm `and perforce the bell crank 118 which, acting through its connected parts, will move the trip arm' `126 into contact with the arm 154, Figs. 8 and 9, disengagingthe hooked end portion of the arm 154 from the roll 156 of the stop arm 149, thereby withdrawing said stop arm from operative engagement with the stop lug 144 of the clutch member 145 and permitting the shaft 94 to be rotated, as will be readily understood. As the shaft `94 thus rotates, the cam 112, Figs. 3 and 4, will act upon the roll 111 of the 'arm 110, and move the lever 108 to cause the jaws to close upon the tack, and, as the jaws can move no farther, further action of the lever 108 will tend to turn the jaw carrier 100 about a fulcrum 99 as `a center, thereby lifting the jaws in their closed position upward from the shoe to withdraw the tack. As the shaft 94 continues its rotative movement the jaw carrier will be moved by the eccentric arm 130 rearwardly substantially in a path as indicated by dotted lines in Fig. 3, until a lowl portion of the cam`112 comes opposite the roll 111,

whereupon the spring 158, Fig. 3, will move the lever 108 and cause the jaws to be opened and drop the tack. In order to prevent the jaw carrier 100 from. tilting during this opening movement of the jaws to release the tack, said jaw carrier is provided with a tail-piece 159, Figs. 3 and 4, which bears against a pin' 160 carried by the cam 112, so that on the upward movement of the end 107 of the arm 108, the jaw carrier will be held infixed position while the jaws open and release the tack. A spring 161, Figs. 3 and 4, acts normally'on the end of the tailpiece 159 to hold the rear end /of the jaw carrier 100 elevated. y 'i a From the construction described it will be apparent that the tack puller, during the action of the machine, normally stands in the position indicated in Fig. 7with the footl portion 114 of one of the jaws in the path followed by the tacks as the shoe is fed positively in the direction jaw, the tack puller is given its initiating 4movement through the means described to scribed, the eccentric 153 raises thearm 154,

the'lower end of which is in engagement at this time with the roll 156 of the stop arm 149 and thereby places the shoulder 151 in the path of the stop lug 144 on the clutch member 145, the -construction being such that as the shaft completes its movement the clutch member 145 is stopped, disengaging the driving Apower from the shaft 94, and the tack puller, with its jaws still open, is moved downward and forward into position as indicated in Fig. 7. j

' Thev characteristic movement of the tack puller is approximately indicated by the diagrammatic -view in Fig. 12, wherein at of feed by the Spudger, and, upon contact of a tack with V the -the point a the jaws are in position, as indicated in Fig. 7, ready to be engaged by and close upon a tack; and as the jaws rise in response to the action hereinbefore described, they follow the path indicated by the arrows, in Fig. 12, to a point b in pulling the tack, and at the point c the jaws open to release the tack, after which, the jaws still being open, they move in the direction of the arrow back to the point a.

The action thus far described contemplates that the foot of the operator remains on the treadle,'but, should the operator take his foot from the tradle, the stop arm 142 will move to the left, from the position indicated in Fig. 9to that indicated in Fig. 8, a plunger 162 at such time striking a finger 163 connected to the arm 154, thereby dis- .engaging the hooked end 155 of said arm from the roll 156 of the stop arm 149 and permitting said stop arm to ni ave into position indicated in'Fig. 8, so that as the shaft 94 rotates, as hereinbefore described, the stop -lug 144 engages the shoulder'of the stop arm 142 and brings the machine to rest with the tack puller in its upward retracted position, substantially as indicated at the 1 point b, Fig. 12, and as indicated also in Fig. 4.

n order that the tacks may be appropriately discharged from the machine without interference with its working parts, the back gage 83 and its carrier 82 are provided with an opening 164, Figs. 1, 3 and 4, into which the tacks may drop and from which they may be discharged by a suitable conduit or other connection.

Since the tack pulling end of the tack puller moves in the path indicated by dotted lines in Fig'. 3, the end 116 of the arm 115 will follow a like course, and in order that it ma bel returned to its initial position opposite the end of the arm 117 when the tack puller returns to its initial position, as indicated in Fig. 7, there is provided a returning finger 165 secured to the fulcrum stud 119 on which the bell crank lever 118 is fulcrumed, the end of said returning finger being projected, as indicated in Fig. 11, to properly position the end of the arm on the return movement of the-tack puller to initial position.

From the construction described it will be noted that each of the seriesjof stitches contemplated. by the present invention is preferably formed after each double feed movement and that the channel of the insole is tempered or.moistened by. the moistening liquid flowing from the tank through its conduit to the channel guide, and the lasting tacks are removed so that the shoe is not only free from the objectionable presence of these obstructions to the action of the welter, but'the channel of the insole itself is properly tempered or moistened to facilitack with the tack tate the passage of the needle during the stitching of the welt to the upper and insole.

Obviously many changes may be made in the details of construction without departing from the true'spirit of the present invention which is definitely set forth by the claims.
